Urlacher's availability for Cards game in doubt

Brian Urlacher missed his third straight practice with a strained calf muscle, casting doubt on whether he will play in Saturday night's third preseason game.
"Right now, he's not ready to go, so we will watch that," coach Lovie Smith said. "But in time, he will be. Nothing serious with him. We never put any players out there until we feel like they can really play up to their potential. We're not quite there right now, but we'll get there in time."
Later, when asked more directly whether Urlacher would play against Arizona, Smith said: "We would like for all of our guys to practice before they play, but if we feel like a guy is ready to go and he's one of our best guys that can help us win, we'll play him then. That isn't the case with Brian. Brian right now needs to practice. We're not playing Detroit right away."
